I use mite paper, I use ca powder to knock off the mites, i freeze the excelsior in freezer before using, i use repashy media, i keep in light bulb heated and air pump ventilated cabinet, i use clean and new plastic culturing containers ( commercial for culturing) , keep at about 75 degrees, now i think they dont have enough humidity and i am taping the covers to keep humidity up, I spend more time culturing and more money buying ffs than I want to keep track of, this is insane, I hope the higher humidity makes a difference, I am willing to bet more than one hobbyist has been driven out of the hobby by these problems, when I used to use coffee filters I had more success (maybe i should go back to those?). It shouldn't be this hard. Just had to vent. Anyone with foolproof methods. Yes, I do have mites, does anyone have any success using miticide that is sprayed into the cultures?
